'lO ALLIWHOM Il'. MAY (IONCERN:

Be it known that I, ORRIN STONE, of Ionio., in the county of Ionia, and State ot' Michigan, haveinventei certain new and useful Improvements in 'Cultivators and I do hereby declarethe following to be n full, clear, and exact description of the same, reference being hed to the'nccompanying drawings, making a part of this specification, in which- Figure 1 represents a top plan, and Figure 2 represents a side view, with the wheel removed to show the parte behind it.

Similar letters of reference, where they occur in the separate figures, denotelike parts ofthe Vmachine both of thel drawings. Y

Myinvention relates to a eultivatorin which there are twofrnmes, viz, an upper iixedfraxne, and an under hinged frame, the'latter hinged to the former, so as to be raised and lowered thereon, so tltat the driver, from his sent, by a lever and other operating parts, may raise and lower the hinged frame that carries the cultivator' teeth or ploughs at pleasure, and so that thohinged frame sh'allbe drawn 'or carried by the fixed frame.

To enable others skilled in the art to make and usemy invention, I `will proceed to describe the saulehvith reference to the' drawings.

A is an axle supported in two carrying-wheels B B. `'.lo this axle are secured the tongue C,V the braces D D,

Vand a cross-timber, E, which, being firmly united together, constitute the main or xed frame.

Underneath 'thofixed frame there is a hinged or yielding frameF,-to which a serie's of standards, G, is

attached, each standard having upon it one or more shoes,- teeth, or ploughs, H, of such shape and form as may be'found most efficient for the purpose of cultivating n crop, or ploughing furrows; said standards bcingbraced v against the resistance of .the drag by rods I, or otherwise. The frame is hinged-to the fixed frame through the intervention of the rods orA braces a attached to the cross-timber E; thence extending downward to where a loop or deadeye, Z1, is formed.; and `thence extending rearward and upward-to the axle A, where it is fastened.

And, thoughvI have shown these braee-rods animado in qne piece, they may he made in two pieces united at b,-

nt which points the under fra-me is hinged by its`loops or dead-eyes cf lA tongue anguille-piece, J, isl hinged, at d, to the. under yielding frame, and the forward end ofl this guide-piece or secondary tongue is fastened to the main tongue C, to draw und guide the yielding frame by.

The drivers seat, K, is fastened On to the rear cndof the tongue C, which'projects beyond and in rear of the marin axle, so that the weight of the driver, when in his sent, may aid to balance the machine.

To the axle A is hinged a. lever, L, which entends upward, so as to be convencntlyreached and operated n by the driver in his'seat. And on thislever L there 4is ahe'nt orf-curved arm, e, to which one end of u cord or chain,f, is attached, which cord or chain, -after yp'n'ssirrglevers pulley-w l\eel,g, in or on th'o tongue, extends down, and is fastened to the'hinged frame F, by which -c-ontrivanee'thc said hinged frame mayfbe raised, held up, or let down by the driver at his pleasure. 'Upon the frame F there is a foot-board, M, for the feet of the driver, who may, by bracing upon the foot-board, hold the ploughs td the ground, or press them deeper therein, if required. i i i Whenthe ploughs are raised up, the parts connected to them, and by which they are operated, will be in the position shown by the red lines in g. 2.

Having thus fully described myinvention, what Ielaim therein .as new, and desire to secure by Letters Patent, is 4 The combination of the fixed and the yielding Tramos, when united together by flexible connections, and

i the under or yielding one is made capable of being raised and crried by the fixed one, inthe manner and for the purpose herein described and represented. p
